[-1210947904]BACKEND[0]: fd 40 has revents 0x00000008, but hasn't been handled.

Anyone who has seen this before?: [-1210947904]BACKEND[0]: fd 40 has revents 0x00000008, but hasn't been handled. It happens rather sporadically in a Roxen production server (the same one we just upgraded to bleeding edge Pike); in fact, it's the first time I see it. The server appears to hang at that point, so my watchdog script (external) kills the server and restarts it after that. -- Stephen.

GC fatal
by Stephen R. van den Berg 22 Apr '10

22 Apr '10

The following error has been occurring in all 7.8 Pike versions for the past 9 months (at least). I have a production machine running Roxen which crashes on an error like this roughly once a day. I'm willing to make custom changes to the production environment in Roxen and/or Pike to track this one down. Things that slow down the production environment for more than a factor of three are not acceptable. Any suggestions on how to tackle this problem? /data/src/gpike/src/gc.c:2519: GC fatal: Marked a thing without refs. **Block: 0xab493890 Type: object Refs: 0 **Got gc marker at 0xbcacbb0: flags=0x00000 refs=0 weak=0 xrefs=0 saved=-1 frame=(nil) **Program id: 66369 **The object is not on the object link list. **The object is destructed but program found from id. ******************* **Looking for references to 0xab493890: **Done looking for references to 0xab493890, found 0 refs.

Pike7.6 and inetd Outputs null byte on Debian Lenny (5.0)
by redax＠redax.hu 13 Apr '10

13 Apr '10

Hi, I'm just upgraded a system from a prior debian to the recent one (from etch /4.0 to lenny/5.0 ) and I had a script which is run by inetd. it was worked so far, but now it outputs a null byte (\0) to the stdout even if the script does not writes to the stdout. if I run the _SAME_ script on an older system, it works no null byte, from Shell, it works, again no leading null byte. just from inetd. I also tried to change bsd inetd to rlinetd, same effect. do you have any idea what makes that extra null byte? Thanks, Redax
